Hmm...this looks like RenderWidgetHostViewChildFrame has an own-relationship
with |frame_connectgor_|.

Why don't we just use a scoped_ptr<CrossProcessFrameConnector> frame_connector_
here and not bother with the Destroy() method? Seems cleaner than having a
self-deleting function in CrossProcessFrameConnector.

There are several empty methods here, why not keep them in the header file only?
